Description

Technical Field

[0001] This utility model relates to the field of soft capsule preparation technology, specifically a novel soft capsule extrusion and degranulation device. Background Technology

[0002] The production process of soft capsules typically includes steps such as extrusion molding and degranulation. The separation part usually includes two separating rollers with a gap between them. The capsule skin containing the soft capsule can fall between the two separating rollers, and the soft capsule is separated from the capsule skin by the counter-rotation of the two separating rollers. This method of separating the capsule skin by rotating the separating rollers and relying on friction can easily result in separation residue, affecting the separation effect. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a novel soft capsule extrusion and degranulation device.

[0004] The technical solution of this utility model is as follows:

[0005] A novel soft capsule extrusion and de-granulation device includes a support frame and an extrusion roller and a pull roller rotatably mounted on it. The axes of the extrusion roller and the pull roller are horizontal, and their left and right gaps are opposite to each other. The pull roller is connected to a drive motor via a compensator. Based on the above structure, the rubber sheet with soft capsules can pass around the lower side of the extrusion roller and the upper side of the pull roller in sequence. When the pull roller rotates, it pulls the rubber sheet to press and adhere it to the lower side of the extrusion roller. Under the action of the extrusion roller, the soft capsules on the rubber sheet are pushed downwards away from the rubber sheet, thus completing the de-granulation of the soft capsules. Through the cooperation of the extrusion roller and the pull roller, the method of extruding the soft capsules by the extrusion roller effectively ensures the fullness of the de-granulation work.

[0006] The compensator comprises a first connecting shaft and a second connecting shaft arranged coaxially. One end of the second connecting shaft is provided with a cylindrical groove. The outer diameter of the first connecting shaft is smaller than the inner diameter of the cylindrical groove, and one end of the first connecting shaft extends into the cylindrical groove. A worm spring is provided between the outer ring and the inner wall of the cylindrical groove. The drive shaft of the drive motor and the stretching roller are respectively connected to the ends of the second connecting shaft and the first connecting shaft that are opposite to each other. Based on this structure, the transmission connection between the drive motor and the stretching roller is an elastic flexible connection to prevent the rotation of the stretching roller from forcibly tearing the rubber. At the same time, it allows the rubber to better adhere to the extrusion roller under the action of the stretching roller, further ensuring the threshing effect.

[0007] As described above, in a preferred embodiment of the novel soft capsule extrusion and granulation device, to ensure that the first connecting shaft and the second connecting shaft can maintain a stable coaxial rotational relationship under the action of the worm spring, the bottom of the cylindrical groove is provided with a slot whose inner diameter is adapted to the outer diameter of the first connecting shaft, and the end of the first connecting shaft is inserted into the slot.

[0008] As a further preferred embodiment, in order to facilitate a more convenient connection between the drive motor and the second connecting shaft, and between the stretching roller and the first connecting shaft, the drive motor's transmission shaft and the second connecting shaft, as well as the stretching roller and the first connecting shaft, are all plugged in and snapped together.

[0009] Preferably, to facilitate replacement in case of worm spring failure, the inner and outer ends of the worm spring are respectively inserted and fixed to the outer ring of the first connecting shaft and the inner wall of the cylindrical groove.

[0010] As described above, in a preferred embodiment of the novel soft capsule extrusion and degranulation device, in order to ensure the pulling effect of the stretching roller on the rubber and prevent relative sliding between the rubber and the stretching roller, and thus ensure that the rubber can better fit with the extrusion roller under the action of the stretching roller, the stretching roller includes a columnar body, and the outer ring of the body is provided with a plurality of outwardly protruding protrusions.

[0011] As a further preferred embodiment, to prevent the protrusion from pulling the rubber sheet onto the pulling roller when it rotates, and to ensure that the protrusion can smoothly detach from the rubber sheet when it rotates to the lower side of the body, the outer end of the protrusion is arc-shaped and tilted towards the side opposite to the rotation direction of the pulling roller.

[0012] As described above, in a preferred embodiment of the novel soft capsule extrusion and degranulation device, a capsule box and a waste glue box are respectively provided below the extrusion roller and the stretching roller to achieve centralized collection of the separated soft capsules and waste glue.

[0013] As a further preferred embodiment, in order to ensure that the separated soft capsules can fall smoothly into the capsule box, a material collection trough is also provided at an inclination between the extrusion roller and the capsule box.

[0014] The beneficial effects of this utility model are as follows: This utility model is a novel soft capsule extrusion and threshing device. The rubber sheet containing the soft capsule can sequentially pass over the lower side of the extrusion roller and the upper side of the pull roller. When the pull roller rotates, it pulls the rubber sheet to press tightly against the lower side of the extrusion roller. Under the action of the extrusion roller, the soft capsule on the rubber sheet is pushed downward away from the rubber sheet, completing the threshing work. Through the cooperation of the extrusion roller and the pull roller, the method of extruding the soft capsule by the extrusion roller to complete the threshing work effectively ensures the fullness of the threshing work. The setting of the compensator makes the transmission connection between the drive motor and the pull roller an elastic and flexible connection, preventing the rotation of the pull roller from forcibly tearing the rubber sheet. At the same time, it allows the rubber sheet to better adhere to the extrusion roller under the action of the pull roller, further ensuring the threshing effect. Attached Figure Description

[0024] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0025] Example

[0026] This embodiment provides a novel soft capsule extrusion and degranulation device; see [link to documentation]. Figure 1It includes a support 1 and a squeezing roller 2 and a stretching roller 3 rotatably mounted on it. The axes of the squeezing roller 2 and the stretching roller 3 are horizontal and the left and right gaps are relatively opposite. The stretching roller 3 is driven by a drive motor 5.

[0027] Based on the above structure, the rubber sheet with soft capsules can pass sequentially around the lower side of the extrusion roller 2 and the upper side of the stretching roller 3. When the stretching roller 3 rotates, it pulls the rubber sheet to press and adhere it tightly to the lower side of the extrusion roller 2. Under the action of the extrusion roller 2, the soft capsules on the rubber sheet are pushed downwards away from the rubber sheet, thus completing the granulation of the soft capsules. Through the cooperation of the extrusion roller 2 and the stretching roller 3, the way in which the extrusion roller 2 squeezes the soft capsules to complete the granulation work effectively ensures the fullness of the granulation work.

[0028] In this embodiment, as a preferred implementation method, combined with Figure 2 and Figure 3 To ensure the pulling effect of the stretching roller 3 on the rubber and prevent relative sliding between the rubber and the stretching roller 3, thereby ensuring that the rubber can better fit with the extrusion roller 2 under the action of the stretching roller 3, the stretching roller 3 includes a columnar body 31, and the outer ring of the body 31 is provided with a plurality of outwardly protruding protrusions 311.

[0029] As a further preferred embodiment, in order to prevent the protrusion 311 from pulling the rubber sheet onto the pulling roller 3 when the pulling roller 3 rotates, and to ensure that the protrusion 311 can smoothly detach from the rubber sheet when it rotates to the lower side of the body 31, the outer end of the protrusion 311 is arc-shaped and tilted toward the side opposite to the rotation direction of the pulling roller 3.

[0030] In this embodiment, as a preferred implementation, in order to achieve centralized collection of the separated soft capsules and waste glue, capsule boxes 7 and waste glue boxes 8 are respectively provided below the extrusion roller 2 and the stretching roller 3.

[0031] As a further preferred embodiment, in order to ensure that the separated soft capsules can fall smoothly into the capsule box 7, a collection groove 6 is also provided at an inclination between the extrusion roller 2 and the capsule box 7. The soft capsules that fall under the pressure of the extrusion roller 2 can fall into the collection groove 6 and slide along the collection groove 6 into the capsule box 7.

[0032] In this embodiment, as the core technical concept of this utility model, the drive motor 5 is connected to the stretching roller 3 through the compensator 4.

[0033] Specifically, combining Figure 4 and Figure 5The compensator 4 includes a housing and an internal compensation unit. The compensation unit includes a first connecting shaft 41 and a second connecting shaft 42 coaxially arranged. One end of the second connecting shaft 42 is provided with a cylindrical groove. The outer diameter of the first connecting shaft 41 is smaller than the inner diameter of the cylindrical groove, and one end of the first connecting shaft 41 extends into the cylindrical groove. A worm spring 43 is provided between the outer ring and the inner wall of the cylindrical groove. The worm spring 43 has a spiral structure and is located between the outer ring of the first connecting shaft 41 and the inner wall of the cylindrical groove. Its inner and outer ends are respectively connected to the first connecting shaft 41 and the inner wall of the cylindrical groove. The drive shaft of the drive motor 5 and the end of the stretching roller 3 both extend into the housing and are respectively connected to the ends of the second connecting shaft 42 and the first connecting shaft 41 that are opposite to each other. Based on this structure, the transmission connection between the drive motor 5 and the stretching roller 3 is an elastic flexible connection to prevent the rotation of the stretching roller 3 from tearing the rubber hard. At the same time, it allows the rubber to better adhere to the extrusion roller 2 under the action of the stretching roller 3, further ensuring the threshing effect.

[0034] As a preferred embodiment, in order to ensure that the first connecting shaft 41 and the second connecting shaft 42 can maintain a stable coaxial rotation relationship under the action of the worm spring 43, the bottom of the cylindrical groove is provided with a slot whose inner diameter is adapted to the outer diameter of the first connecting shaft 41, and the end of the first connecting shaft 41 is inserted into the slot.

[0035] As a further preferred embodiment, in order to facilitate the connection between the drive motor 5 and the second connecting shaft 42, and between the stretching roller 3 and the first connecting shaft 41, the drive shaft of the drive motor 5 and the second connecting shaft 42, and the stretching roller 3 and the first connecting shaft 41, are all plugged in and snapped together.

[0036] Preferably, to facilitate replacement in case of worm spring 43 failure, the inner and outer ends of the worm spring 43 are respectively inserted and fixed to the outer ring of the first connecting shaft 41 and the inner wall of the cylindrical groove.
